CUSTOMER SATISFACTION IS GROWING EVER MORE IMPORTANT In an era of 24/7 connectivity, delivering on customer expectations is more important than ever. That’s why the customer-obsessed heroes who make up Team Magenta are our most powerful differentiator.

IT TAKES PUBLIC AND PRIVATE SUPPORT TO ADEQUATELY ADDRESS THE DIGITAL DIVIDE Internet infrastructure is an essential part of a digitally inclusive society, but it’s just one piece of the puzzle.

As the U.S. takes steps to close the digital divide, including a $65 billion investment to improve broadband infrastructure through the American Jobs Plan, at T-Mobile, we’re continuing our critical efforts to support digital equity through our five-year $10.7B Project 10Million commitment.
